IMPROVEMENT lIN WHIFFLETREE ATTACHMENTS.

' Specification forming part of Letters Patent No. 114,298, dated February 29, 1876; application filed J une 7, 1875.

To all lwhom it may concern e, v

Be it known that I, SAMUEL G.PUR1NT0N,

` of Somerset, in the county of Bristol and tree constructed and secured to the vehicle inv the manner hereinafter described.

In the vaccompanying sheet of drawings, Figure l is a side view of -my invention, partly in section; and Fig. 2, a top view of same. f

Similar letters of reference indica-telike parts in the several figures! As is Well known, the whole strain in drawing a vehicleisbrolight upon the transit-bolt, which secures the whifetree to the cross-bar of the thills, so that when this bolt is broken when driving a vicioushorse, great danger occurs to the occupant of the vehicle. To obviate this danger, and at the'same time render the whiftletree perfectly adjustable under all circumstances, I divide the-cross-bar A ot' the thills B, transversely, by a horizontal slot, in Which is fitted an iron connecting lin'k G, this link projecting at right angles to the iront edge of the crossbar, as shown in the drawing. The whifetree D has vfitted to its center a stud, d, which is secured in the opening in the link (l, or the Whiftletree may be fitted directly in said opening. Secured to the link C, and extending to the rear, is a rod, E, of metal. To the rear end ofthis rod is a `cross-bar, e, to one end of which is secured a draw-rod, F, the other end of said rod extending and aflixed to the rocker G. From the axle H extends a drawrod, I, which is attached to the other end of the cross-bar e, and thence to the cross-bar A. The drawrod I, above described,"and the shafts B are rigidly attached to the axle in any suitable manner that will allow of the necessary motions thereof.

My whiftletree being constructed substantially as I have described it, the stud d in the whifetree D is placed Within the opening of the link C; and the rod E being secured t0 the center of the cross-bar e, and the drawrods F and Il being affixed to the cross-bar, axle, and rocker, as before described, all the strain that is brought to bear upon the Whiflietree by the team is received byV the rod E, which conveys it to the cross-bar e, and thence the strain is dividedbetween the draw-rods F and I, and is finally borne by the axle H and rocker G, the stud d in the whiflietree D acting as a guide and center-pin merely, and thecross-bar c acting to some extent as an evener, tending to equalize the strain in whichever position the Whifetree may assume.

From the foregoing description of the-construction and operation of my whiftletree attachment, it will be seen that the strain is so eqnalized that it would be nearly impossible to break the connection between the Whiftletree. and vehicle. It will also be observed that the Whiflietree has full freedom tomove and swing, not only back and forth, but to meet the rise and fall of the shafts. This takes away very largely from the st-rain generally borne by whifiietrees. i

VOne or more springs', m, are placed behind the Whifietree, which are designed to' keep `the links tight when there is no draft on the Whiietree.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The combination, with the whiftletree, of the slotted cross-bar, link, and draw-rods, substantially as specified.

2. The combination of the cross-bar A, link C, rods E F, bar e, and draw-rod I, substantially as described.

3. The combination ofthe cross-bar A, link G, rods E F, bar e, and draw-rod I with the Whiftletree, axle, and rocker G, substantially as and for the purposespecied.
